Studies on preservation of fish in refrigerated sea-water

Storage characteristics of oil sardine (Sardinella longiceps), mackerel (Rastrelliger kanagurta) and seer (Scomberomorus guttatus) in refrigerated sea-water (RSW) were studied in comparison with their storage in crushed ice. Oil sardine stored in RSW was found to be comparable to iced ones only during the initial stages (up to 2 days) of storage and on further storage the former was found to be inferior to the latter. RSW can be advantageously employed for preservation of mackerel and seer. Mackerel and seer could be stored in RSW in acceptable condition for 4 to 6 days and 12 to 14 days respectively.
